Section 1 Flashcards
Immunology
Study of structure and function of immune system
Immunity
- The process by which the body recognize foreign substances and neutralizes them to prevent damage
- immunity is specific = immune cells seek out and destroy specific invaders - immunity has memory = immune cells produce substances that remember and more easily destroy return offenders
Antibodies
Immunoglobulins is another name
- good guys
Antigens
- bad guys
Cellular immunity
Provided by T lymphocytes
- cytotoxic or killer T cells
- helper T cells
- suppressor T cells
Humoral immunity
B lymphocytes produce and secrete antibodies/immunoglobulins
IgG,M,A,D,E
Neutrophils
Phagocytic cells they are the first responders
Eosinophils
They offer the greatest protection against parasites
Basophils
Complement the actions of mast cells in allergic reaction
Monocytes
Differentiate into macrophage when they move into the tissues
Innate immunity
Is the first responder to insult, the response is rapid and can be initiated by many different pathogens without prior exposure.
- functions to prevent microbe colonization, entry, and spread
Natural immunity
We have some natural or species specific immunity
Ex- cannot get canine distemper, only dogs get it
Adaptive immunity
This is a slow response it is specific
- Key properties
- specificity
- diversity
- memory
- self and non-self recognition
Acquired immunity
This is obtained after birth
- may be passive = obtain through placenta or breast milk ,Gamma globulin
- may be active = have a disease or get it through vaccination.
Immune deficiencies
- Many are generic there are B, T, and combined efficiencies
- some are acquired secondary to another illness such as leukemia or AIDS
